[2] In December 2009, Tasair was speculated to be involved in charter flights hired by a PR firm for Japan's 'Institute of Cetacean Research' whaling company to spy on anti-whaling vessels, an action later condemned by the Australian Government and deemed illegal under a 2008 Australian Court order preventing any assistance to whaling operations.

Tasair incurred hefty legal bills dealing with the CASA probe and another by the Environmental Defender's Office that included demands that documents be surrendered.
Regular freight services were conducted between Hobart, Devonport, King Island and Burnie.
The Cessnas were used to carry bushwalkers to remote locations; for sightseeing; and for flight training.
